UNITED fSTATES GEORGE B. BOUGHTON, OF ST. LOUIS, MISSOURI.

GARAGE DOOR AND OPERATING MEANS THEREFOR.

Application filed. September 6, 1921. Serial No. 498,835.

To all whom z't may concern:

Be it known that I, GEORGE B. BOUGHTON, a citizen of the United States, residingat St. Louis, in the State of Missouri, have 1nvented certain new and useful Improvements in Garage Doors and Operating Means Thereforyan d I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and This invention relates to an'improved construction in garage doors and means for operating the doors and one object of the invention is to provide improved means for swinging the door upwardly and inwardly to a raised or open position and to provide .a construction whereby springs may be provided to assist in the movement of the door to the raised position.

Another object of the invention is to provide an improved arrangement of pivotally connected bars or strips which serve to guide the sections of the door in their upward movement to an open position and also serve to support the door in the raised posi tion.

Another object of the invention is to so construct this device that springs which serve to assist in swinging the door to the raised position may be mounted upon drums with which certain of the bars are pivotally connected.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a viewlooking at the inner face of the door with the door closed.

Figure 2 is a vertical sectional view taken along the line 22 of Fig. 1.

Figure 3 is a view similar to Fig. 2 showing the door moved partially into an open position.

Figure t is a sectional View through the spring carrying drum.

The door is to be used in connection with agarage 1 having a doorway provided with tracks 2 at its sides and adapted to receive the rollers at the lower ends of the main door section 3. This main door section has its upper end hingedly connected with the upper or auxiliary door section 4 by hinges 5 so that the door sections may be swung out of alinement with each other and then again into alinement when moving upwardly from a closed position in which it extends vertically to an open position in which it will extend horizontally a short distance beneath the roof of the garage as shown inmy prior Patent No.1,34:1,-

Standards 6 are. positioned against the sides of the garage and each carries a drum T'which is provided with a ,pin extension 8 which passes through an opening formed in the upper end of the bracket 9, the brackets serving to brace the. drum. Main bars 10 are pivotally connected with the strips 11 which are secured against the inner face of the main door section 3 and these bars 10are loosely mounted upon the-spin extensions 8 of the drums. Links or bars 12 are pivotally connected with brackets 13 secured to the upper or auxiliary door section and these links or bars 12 are provided with a plurality of openings at their inner endsso that these links may be pivotally connected with the bars 10 at a desired angle. By providing this construction, the door sections may have pivotal movement as they swing upwardly and during this movement the links and bars 10 may swing towards and away from each other. Springs 14 are provided so that the door section 3 will normally extend at right angles to the bar 10 and will be returned to this position, when the door is in either the raised or lowered position. When the door section 3 is in the position at right angles to the bars 10, the section 4: ofthe door will be held in alinement with the section 3 but will move into angular relation to the same when the door section 3 is out of a position at right angles to the bars 10;

' gaged by fasteners 20 carried by the standards 6. Since the springs are under tension when the door is in the closed position and tend to move the arms 10 upwardly, these springs will serve to assist in swinging the arms and door sections upwardly in opening the door. The usual counterbalance weights 21 are provided. these weights being each carried by a cable 22 which passes over a pulley wheel 23 and has its ends connected with the lower end portion of the door section 3 as shown at 24. There has thus been provided a door operating mechanism so constructed that the door may be easily swung upwardly from a vertical to a horizontal position.

I claim:

1. In a structure of the character described, a door having a main. section slidably and pivotally mounted at its lower end, an upper door section hingedly connected with the upper end ofthe main section and operating means comprising pivotally mounted bars loosely connected with the upper portion of the main door section, links pivotally connected with the bars and lower portion of the upper door section, a-IIns pivotally connected with said bars and extending upwardly therefrom, sleeves loosely connected with said arms, and coiled. springs having arm extensions fitting into said sleeves and tending to. swing the bars upwardly to raise the door.

2. In a structure of the character described, a door having a main section slidably and pivotally mounted at its lower end, an upper door section hingedly connected with the upper end of the main section, and operating means comprising bars pivotally mounted and having loose connection with the main door section, springs connected GEORGE B.
